Pannoniasaurus
Pannoniasaurus was a mosasaur, a kind of marine lizard, but it lived in rivers, not the sea! It had a flat, crocodile-like skull and could grow up to 6 meters long. This unexpected hunter lived in what is now Hungary during the Late Cretaceous.1

Pannoniasaurus is the first mosasauroid ever found that lived in freshwater, like a river dolphin.1
Its name means 'unexpected' because scientists were surprised to find a mosasaur in freshwater rocks.1
It had a flattened, violin-shaped snout and teeth with ridges, like a crocodile.1
Fossils of many individuals, from babies to adults, were found together in a flood deposit.1
Pannoniasaurus lived alongside dinosaurs, pterosaurs, turtles, and crocodiles in a tropical floodplain.1
Its tail was not flattened like other mosasaurs, so it probably swam more like a land lizard.1
